Table 1. Results of the morphogenesis and proliferation screens.

Morphogenesis results are presented as the number and percent of mutants with a given M score. Results were omitted for 4 mutants with inconsistent results and 17 mutants with poor growth on Spider medium. Proliferation results are presented as the number and percent of mutants with a given doubling time, also expressed as the number of standard deviations (s.d.) greater than that of wild type.
